ABSTRACT:
A process, and apparatus for recovering cellulose fibers from contaminated paper-plastic mixtures by exposing the mix to controlled wetting to increase the weight of paper cellulose components relative to the weight of the plastic components; subjecting the wetted mixture to abrasive forces to fiberize the paper component and then separating the fiberized paper cellulose product from the plastics and other contaminants, to yield several classified products showing distinctly improved quality.
